Reciprocating compressor
Thread Content
Help: 1. How is the sealing performance of the air valves in reciprocating compressors tested? 2. Relevant documents for the installation and commissioning of reciprocating compressors
1. The types of gas valves vary, and the experimental methods differ as well. It’s best to send pictures; it’s more intuitive to communicate by looking at them. 2. All shall be in accordance with the equipment user manual. For reference.
JB T 53175-2000 Quality grading of ring valves for reciprocating piston compressors; JB T 7240-2015 Technical requirements for major components of general-purpose reciprocating piston air compressors; QSY 06506.13-2016 Technical specifications for rotating equipment in petroleum and chemical engineering – Part 13: Reciprocating compressors; SH T 3143-2012 Technical specifications for petroleum and chemical reciprocating compressor projects; SH T 3544-2009 Construction and acceptance specifications for opposed reciprocating compressor units in the petroleum and chemical industry; “Compilation of Chinese Machinery Industry Standards – Compressors Volume (Upper and Lower)”
1. The sealing performance of air valves is generally tested using kerosene for leak detection; of course, water is sometimes used as well； Generally, leaks are allowed within 5 minutes, but the rate must not exceed 10 drops per minute. 2. For reference materials, see what is stated on the 4th floor
We mostly use kerosene for leak testing.
1. It’s just water; we use water for testing every time we replace the compressor valves, and there are basically no problems. 2. The compressor manufacturers provide everything needed for installation and debugging
For testing leaks by pouring kerosene, there is a minimum leakage amount requirement; if that requirement isn’t strict, water can also be used for the test
